Oakland's head coach told SiriusXM NFL Radio on Wednesday that the former Fresno State signal-caller impressed the team with his intelligence, calling Carr "one of the smartest quarterbacks that I have had an opportunity to interview."

Said Allen: "He's very fiery, which you can see on the tape. Although he may not be fiery off the field. And, he's incredibly intelligent."

Despite being nestled behind Matt Schaub and Matt McGloin on the depth chart, Carr has a solid shot to see action as a rookie.
